Specification of Letters Patent.

Patented J 11116 23, 1914.

Application filed January 22, 1908. Serial No. 412,078.

To all whom may concern Be it known that I, OLIVER M. EDWARDS, a citizen of the United States, residing at Syracuse in the county of Onondaga and State of New York, have invented a certain new and useful Improvement in Window- Sash-l-lolding Devices, of which the following is a full, clear, and exact description.

My invention has for its object, a holding device for the window sashes which is particularly simple and economical in construction and highly efficient and durable in use; and the invention consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 illustrates the lower portion of a window sash provided with my invention, portions of the sash being broken away. Fig. 2 is a horizontal sectional View taken on line AA Fig. 1. Fig. 3 is a detail view of the sash holding device seen in Figs. 1 and 2 showing the device in end elevation. Fig. 4 is a detail View showing the interlocking sliding engagement of the rock shaft sections. Fig. 5 is a transverse sectional view, on Fig. 4c, the window sash being omitted.

A is the window frame or casing formed with the usual guideways for the sash to move in opening and closing.

B is a sash having its side margins movable in the guideways, these guideways being formed in the usual manner and being confined 011 one side by the usual removable window stop -a.

D designates the holding device as a whole there being here shown one holding device near each side edge of the window sash B-. Each holding device consists of a locking pawl or dog cZ which is here illustrated as mounted on the outer end of a rock shaft section (Z extending into a recess arranged transversely of the window sash, the shaft section --cZ- beingjournaled in a casing or plate closing the front and outer edge of the recess and together with the walls of the recess forming a closed chamber. The locking dogs cZ coact with suitable strips a provided in the guideways usually on the removable stops a-, each strip having rounding teeth or corrugations with which the contiguous dog -(Z coacts, and each dog being shaped to lit the depressions between the bases of the corrugatlons and also to engage surfaces of the corrugations approaching said depression, see Fig. 8.

Each rock shaft section Z andpawl -d is spring pressed and is operated by means connected thereto to permit a slight rocking movement of the rock shaft relatively to its operating means, and also to permit an axial adjustment of the shaft (Z without disconnecting it from its operating means, in order to accommodate windows of different widths.

As shown the contiguous end of the operating rock shaft section -d and each rock shaft section d are provided with angularly disposed overlapping port-ions having flat opposing faces so arranged or cut away, Figs. 4 and "5, relatively to each other that a limited rotary movement of one section --d d relatively to the other is permitted, and owing to the overlapping of said sections, the lengthwise adjustment of the parts is permitted in order that the rock shaft sections may be extended to fit slightly different widths or window frames. The lapping portions and the sleeve to be described form an interlocking sliding engagement.

d is a sleeve encircling the portion at each end of the rock shaft section d lapping the contiguous end of each shaft section -rZ the sleeve being secured to one of said sections as the section -dby a suitable key.

-c is a spring coiled about each shaft section cl and connected at one end thereto through the sleeve Z and bear ing at its other end against a pin on the end wall of the plate of the holding device D this spring tending to rock the sh aft section to hold the dog cZ in operative position.

The intermediate section of the rock shaftis operated a device O consisting of movable and fixed hand engaging parts 0 and 0 The movable part 0 is connected midway between the sides of the window to the shaft section rZ-, and is located near the stationary part 0"-.

In operation, if it is desired to raise or lower the window, the part 0 is operated to rock the shaft sections to withdraw the dogs (Z from the strips of the casing, against the action of the spring c and when the window has been moved to its desired position, the hand engaging piece 0 is released permitting the pawls to be moved relatively to the spring into operative position.

What I desire to claim as new is:

1. In a window the combination, substantially as set forth, of a frame adapted to receive and hold a sash, a sash movable in the frame, sash holding means mounted at each of the side edges of the sash each means having a movable part in the form of an arm of a rock-shaft to bear against the frame, a shaft for each arm, means connecting such shafts and arms together with a limited movement of one arm relatively to the other, separate means adapted to force each of such arms into holding position against the frame, and operating means adapted to move such arms out of holding position to release the sash for opening or closing the window.

2. A sash holding device comprising a sectional rock shaft, and a holding dog carried by one section of said shaft, said sections having an interlocking sliding engagement, substantially as and for the purpose set forth.

3. A sash holding device comprising a sectional rock shaft, a holding dog carried by one section of the shaft, means for rocking the other section of the shaft, said sections having an interlocking sliding engagement, and a spring arranged to rock the section carrying the dog relatively to the operating section, substantially as and for the purpose described.

4. In a sash holding device comprising a sectional rock shaft, ,a holding dog carried by one section of said shaft, a part for ope'ating the shaft carried by the other section thereof, said sections having interengaging, angularly-arranged parts movable relatively to each other at their contiguous ends, and a spring associated with the dog carrying section tending to hold the dog in engaging position.

5. A sash holding device comprising a sectional rock shaft, a holding dog carried by one section of said shaft, an operating part carried by the other sect-ion of the shaft, said sections having overlapping portions at contiguous ends for permitting lengthwise and limited rotary movement of one section relative to the other, and a spring associated with the dog carrying section tending to hold the dog in engaging position.

(3. A sash holding device comprising a rock shaft, a holding dog carried by one section of said shaft, an operating part carried by the other section of said shaft, the contiguous ends of the shaft sections being disconnected from each other and provided with cooperating, angularly-disposed, surfaces, a sleeve inclosing said contiguous ends and holding the same in operative relation with each other, and a spring associated with the dog carrying section tending to hold the dog in engaging position. 7

7. The combination with a. window sash having a recess in the face thereof, plates associated with the sash and cooperating with the recess to provide a chamber, shaft sections housed in said chamber, one of the sections extending through one of the plates and finding a bearing therein, a dog on the projecting end of said section, the contiguous ends of the sections being disconnected from each other and provided with angularly-disposed overlapping portions, a sleeve encircling the overlapping portions of the sections for maintaining the same in coiiperative relation, a spring encircling the dog carrying section having one end thereof attached to the latter and its opposite end to one of said plates, and being under tension for forcing the dog into engaging position, and a finger piece extending from the other shaft section for rotating the latter and therethrough the dog carrying section against the tension of said spring.
